Good news for the prospect of finding microbes on Mars. Pointing.
Mars. Pointing. His team deployed an autonomous rover mounted drill and sampling device in the Atacama desert to see if it could extract soil samples containing microbes down to a depth of 80 centimeters. That's a little over 2.5 feet. As a comparison samples were also dug up by hand. Through DNA sequencing. The researchers found that the bacterial life samples from both methods were similar, confirming that these hardy bacteria exist and the autonomous extraction method was successful. This test run shores up hope that if similarly, hardy microbes also thrive just below the Martian surface. A robot could find them. However, finding microbial bio signatures on Mars could be very challenging for remotely operated Mars Rover. The researchers found that the subsurface population of bacteria were extremely patchy, correlating with increased salt levels that restricted the availability of water. Appointing put it this way. The Pappy nature of the colonization suggests the rover would be faced with a needle in a haystack scenario in the search for Martian bacteria. Previous studies
